First, installed Mumble v1.2.2 successfully on three machines. On two machines, the Audio Wizard configures the mic and ear piece correctly. The other machine has Nvidia sound chips and will not recognize the mic. But when you go live, you cannot hear anyone and they cannot hear you.

Second, how does one update Mumble v1.2.2 to v1.2.3?

There's already a bug report for that: https://bugs.mageia.org/show_bug.cgi?id=2061
and a forum thread, maybe you could have used the search function?
